Introduction
The Taoglas FXR and FXC series of high-performance NFC (Near Field Communications) antennas are ideal
for IoT and mobile devices and for applications such as contactless payment systems, access control or RFID
systems.

Introduction
The compact, flexible NFC antennas are supplied with adhesive backing for quick and easy installation and
can be mounted inside a plastic device enclosure or on an internal battery. For any NFC antennas that are
attached to the battery, we offer variants with ferrite flux directors to provide isolation from the battery or
other electronic components within the device. Using the antenna on a conductive surface without a ferrite
layer could result in losses on the antenna communication performance.
Introduction
Taking into consideration the many environments that the antenna could be used, Taoglas offers three
versions of each of the FXR and FXC series models. A standard model without ferrite and adhesive backing, a
model with a ferrite layer and adhesive backing and a third model with ferrite and a 75mm Twisted Pair
28AWG cable with ACH(F) connectors.
Introduction
Typical Applications Include:
-
Mobile Devices
Wearable Smart Devices
Payment Terminals
Device tracking and ID systems
Access control
For further optimization to customer-specific device environments and for support to integrate and test this
antennas performance in your device, contact your regional Taoglas Customer Services Team.

* Contact pads are gold plated copper. Base material is polyimide which can take heat from soldering for brief periods suitable for
attaching wires. Additional wire length will affect read range and result in different performance than that detailed in this document.

Characteristics
A test fixture is used to measure the maximum interrogation distance. The
FXC.40.A antenna is
connected to NFC evaluation boards and then placed under the PC material blocks to communicate with
the standard card above them.

When the number of the PC material blocks are carefully adjusted until the reader can no longer read
the sample, that’s mean in this point the FXC.40.A cannot establish communication with the standard

RFID Tags and POS Used for Test
A total of 5 NFC forum tags were used to measure the interrogation distances. The next picture shows
type 1, type 2, type 3, type 4 and type 5 tags, respectively.
Type 1 is based on ISO/IEC 14443A standard and has 96 bytes of memory.
Type 2 is based on ISO/IEC 14443A standard and has 144 bytes of memory.
Type 3 is based on ISO-18092, JIS-X-6319-4 Sony Felica standard and has 9k bytes of memory.
Type 4 is based on ISO / IEC 14443A 1-4 compliant and has 4K of memory
Type 5 is based on ISO-15693 specification, the communication with this NFC Forum Tag type is based on
NFC-V Technology.

The POS machine used for test
The next picture shows the POS machine using to measure the Card emulation performance of the
FXC.40 Series NFC antennas.
ACR122 is a PC-linked contactless smart card reader/writer developed on the 13.56MHz Contactless
(RFID) Technology and followed the ISO/IEC18092 Standard for Near Field Communication (NFC),
supporting not only MIFACE® ISO 14443 A and B cards but also NFC and FELICA contactless
technologies.
The ACR122 is a USB Plug and Play device with CCID compliance. By making use of up to 424 Kbps for
NFC Tag access and full USB speed of up to 12 Mbps, the ACR122 can read and write faster and more
efficiently. The proximity operating distance of ACR122 is up to 5 cm, depending on the type of
contactless tag in use. Operating distance can be extended on request by adding an RF boaster, so the
ACR122 is suitable for logistics and supply chain management.
T6-BU-00-00 is a 13.56MHz high frequency readable and writable device, a USB drive-free RFID reader
card which supports ISO14443 standard protocol Class A card reading and writing read and write. Also,
T6-BU-00-00 is a module that can be set to read and write a chip card that supports the ISO15693
standard protocol.

Matching
The interrogation distances presented here were taken with the antenna connected directly to the
evaluation boards with the optimzed matching circuit. For the NXP PN553 chipset, it is sugguesd using
20ohm impendence of the NFC antenna. Just like below:
As with any matching network the exact circuit and values for an optimal network depend on the
combination of antenna, NFC circuit, any intervening transmission line and the environment presented
to the antenna. These factors are specific to the particular end product.
As a starting point, to achieve the read range results presented here, use the matching network detailed
in the schematic of the evaluation board for your particular NFC chip and keep the antenna free of any
obstruction. Once you can demonstrate successful reads you can then optimize performance as desired.

Read/Write & Card emulation mode
The NFC forum card type 1~5 were used to measure the interrogation distances in Read/write mode. The POS
machine ACR122, T6-14443 T6-15693 were used to measure the interrogation distances in Card emulation mode.
